SchemaTraverser aids in the traversal of the given SchemaType. In some cases (eg avro), it is more performant to create the top-level schema once and then traverse it top-to-bottom, rather than recreating at each node.
This helper trait allows the Row.to function to traverse SchemaType without leaking details of the SchemaType structure.
